Morgan Wallen 'GMA' Interview Rings Hollow, Says Nashville NAACP President

Morgan Wallen explaining on 'GMA' his rationale behind using the n-word is gibberish ... so says the NAACP Nashville chapter president.

Sheryl Guinn tells TMZ ... she believes Morgan's sit-down with Michael Strahan is the result of Morgan being sorry not for what he said but for getting caught using the racial slur. She says it's a travesty Morgan never thought about the meaning behind the hateful word.

What's more ... Sheryl says his white privilege was on full display for never caring to learn the hurt that word causes. And, she's is dismayed by Morgan trying to contextualize the word ... saying he used it in a "playful" way.

Sheryl does believe Morgan can turn things around ... and she has a punch list.

According to Sheryl ... Morgan can make amends by addressing serious issues, like inequality. Morgan broached the subject a bit when he told Strahan "it would seem" country music has a race problem ... though he hasn't thought about it too much.

Sheryl says he can start in his hometown of Nashville ... where Morgan is hugely influential.

The NAACP honcho says while Morgan's at it, he should encourage his community to get vaccinated. Less than 40% of Nashville got the shot ... and it's devastating marginalized communities.
